Matthew states some surprising things to a modern’s way of thinking. The problem is in us (if we don’t understand it). Folks today, if they are going to understand the bible, will need to temporary forsake the Greco-Roman way of thinking in absolutes. There is the Hebrew prophets way of analogical or correspondent thinking about how God is revealing what He is going to do. Sometimes biblical events hearken to future greater fulfillments in unexpectant ways (at least to us). Here is a podcast from Dallas Seminary (which thankfully has transcription) about Matthew’s use of O.T. material.
